During the same time with 〜間(に)

(あいだ)(に) joins two clauses to state that the second (main) clause takes place at the same time as the first (subordinate) clause.

The clauses may have different subjects.

(あいだ) may attach to a noun, adjective, or verb. The verb before (あいだ) is normally non-past 〜て+いる or いる.

When two clauses are joined by (あいだ), they typically cover the same span of time. When に follows (あいだ), the main clause occurs within the same time as the subordinate clause.

English counterparts are “during (the time when)” and “while”.
